Abstract
PURPOSE:To speed up work for backing and turning a machine body in harvesting work, by setting a shorter stroke for lifting a reaping part with the second hydraulic cylinder than that for lifting the reaping part with the first hydraulic cylinder. CONSTITUTION:A combine is driven and traveled to carry out harvesting work. In the process, the machine body is set in a state for backing the machine body by a swash plate 2 in a hydraulic pump (P2) of a hydraulic stepless speed change transmission device (HST). The side of a circuit (K2) communicating with a circuit (K3) of the second hydraulic cylinder (C2) attains a high pressure to lift a reaping part 1. At this time, the second hydraulic cylinder (C2) reaches the stroke end of extending actuation to prevent the reaping part 1 from lifting to a higher level than that. If the HST is set in a state of advance to readvance the machine body, the side communicating with the second hydraulic cylinder (C2) becomes a return side under a negative pressure. Thereby the second hydraulic cylinder (C2) performs contracting actuation by the weight of the reaping part to subject the reaping part to lowering actuation. Since the stroke of the cylinder (C2) is short, the actuation is completed in a short time.
